ASoC: tlv320aic3x: Add multi endpoint support
Support multiple endpoints on TLV320AIC3xxx codec port when
used in of_graph context.
This patch allows to share the codec port between two CPU DAIs.
Custom STM32MP255C board uses TLV320AIC3104 audio codec. This codec
is connected to two serial audio interfaces, which are configured
either as rx or tx.
However, when the audio graph card parses the codec nodes, it expects
to find DAI interface indexes matching the endpoints indexes.
The current patch forces the use of DAI id 0 for both endpoints,
which allows to share the codec DAI between the two CPU DAIs
for playback and capture streams respectively.
